To all y,1o/1,0m 'it may cof/wcm;.'k

Be it known that we, CHARLES B. Sci-Toniannrin and MARTIN L. lilnnrus, citizens of the United States, and residents of lVaterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful improvements in Primary Batteries, oi which the following is a specification.

Our invention` relates to primary batteries and particularly refers -to a cylindrical form of an assembled element battery.

It is the object ofthe invention toy produce a cylindrical kform of battery which shall include av series of four or more annular electrodes arranged one within the other so that the walls of the respective electrodes will be alternately arranged one within the other and so as to aiord two working :faces for each of the electrodes, except the outermost one and whereby four or more electrodes are employed, two of which are of one polarityrand two or more of another, all supported from a common insulative member which in turn is provided with suitable suspending means whereby the unit may be supported within a battery jar. Further to construct this insulating member andthe electrodes supported therefromso that all of the electrodes of one polarity will be mechanically and electrically connected, whereas those of the other polarity will be similarly supported and connected to form the terminal fr the opposite side of the battery.

A. battery of this type will obviously be of greater efliciency than where but two annular electrodes of possibly different construction, are employed to the extent that one in many instances would serve to do the work required for two of the oldstyle. Besides our present form of battery will not occupy as much room and further will be less ex-` pensive to produce.4

With these and other objectsin view the invention resides and consists in the construction and novelv combination and4 arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and pointed outy in the claims hereto appended, it being understood that various changes in the form, proportion, size and minor details of'construction within the scope of the claims may be resorted to without departure from the spirit or sacrificing any of theadvantages of the invention,

Similar characters of reference denote like or corresponding parts throughout theseveralk figures of the accompanying drawings forming a part of this specification/and 'upon which, y y

Figure l shows a central vertical cross section through a form of our invention wherein four electrodesy are employed two of which are negative electrodes and the other s two positive electrodes. Y

s Fig. 2 is a plan view of the assembled element shown in Fig. 1.` l

Fig. 3 is a furtherk central vertical sectional view of a slightly different form of assembled element and Lwherein two negative electrodes are employed as positive electrodes, and y y v F ig. 4 shows a plan view ofthe form of assembled element shown'in Fig. 3.

`Referringin detail to Figs. 1 and 2 represents an insulative supporting member having a suitable centralopening ytherethrough and several smaller holes 7 to accommodatei rods 8 and stems 17a for attaching the annular electrode 9 andl. To the top portion vof this insulating block is secured a'metal hanger 10 that issecured to the insulating block by means of the rod 8 and the nuts 11 mounted thereon; Said hangers are further provided with upwardly disposedv end portions ythat are bent to form hooks 12 to engage the top edge portion of the battery j ar, not shown. A coupling 12aL between e three is attached to the end of one of these hooks and serves for the connection of'another cell or possibly a line wire. This hanger I is further provided with acentral hole through which the threaded stem 13 of the centrally arranged negative electrodek `14,.passes for attachment directlyto the metal hangerby means of the nuts 15 threadably 4mounted upon the s'tem.` ,This central electrode is preferably in the form of a cylindrical basket made vup yof an louter annulary metal wall having openingstherethrough and provided with atop and 'bottom cap that fits against the opposite end portions of the annular metalwall. This basket is `filled with depolarizing 'material of either thel powdered,y granularorsolidifiedform, thus forming anegative, electrode. s c

Thecuter annular form of negative electrode, before mentioned, and shown in Filgs.

1 and 2, includes an innerl and outer annu ar metal wall which may be perforated or formed of woven wire mesh as preferred. vThe ends of these electrodes are inclosed, and the top end is held against the underside of the insulative support, while the lower end is engaged by the hook ends of the rods 8. The nuts 11 of the rods are obviously tightened in a manner to draw the element upto hold the electrode in position. This element, like the central member, is iilledwith a suitable de polarizing material of any kind andthus cons'titutes the outer negative electrode in this `form of assembled element.

This assembled element, shown ink Figs. 1 and 2, includes two annular positive elements 1'? and 18, the inner and thicker `one of which is arranged central between the two negative electrodes 14 and 9, while the outer and thinner one 1S is exterior of the negative electrode 9 and servesy to be worked upon from the outer face of the negative electrode 9. These positive or zinc electrodes are provided with a single terminal wire 16 which may be connected to a bridge 19, as

shown inFig's. 1 and 2, or to the suspending rod 21 indicated by dotted lines in Fig, 2 and whereby the two electrodes are electrically connected. l

The modified construction shown in Figs. 3 and et includes two annnlarreceptacles or compressed Velements forming the negative electrodes and both of these are connected to the insulating block 5 by means of rods 8 similar to those employed in Fig. 1. These elements are formed of perforated metal and include a filling of depolarizing material similary to that used'in the before mentioned negative electrodes. i

In this form of the invention we` have shown the central electrode 2O as4 being a positive electrode provided with a central suspending rod 21 which is connected tothe members 19a by a nut and also intended to form a hanger so that the assembled elements may be hung from a battery jar cover. This suspending rod may be used as' a ter# minal connection, ifdesired in which case thewire 16 would be connected thereto as shown in Figs. 3 and 4. In addition to this central zinc we employ two annular members 17 and 18, one ofwhich hangs between the twonegative electrodes 9 and 22 and the other being placed around the outer nega# tive electrode 9. All three of the positive electrodes are supported from the' cross meniber 19aA constituting one pole of the battery, and to which the terminal wire 16 may be connected. ln this instance, the positive electrodes are all connected to the cross members, while the negative electrodes are suit* ably connected by bridges 10a' and are adapted for the connection of a terminal wire 12b..

Thus it will be seen that the invention is susceptible of modiication, along this line, and may employ either a positive or negative central electrode as the central element and may be formed of four or five electrodes as preferred. The improvement broadly resides in the employment of four or more annularforms of electrodes of two opposite polarities alternately arranged one between the other in a manner to form a very compact and'eificient battery. e

Having thus described our invention what we claim and desire to secure by Letters Patent is 1. In a vprimary battery of the class described, the combination of an assembled element, comprising a single insulating supporting member,` two or more annular electrodes of one polarity directly connected to the under side of the insulative'supporting member, two or more annular electrodes of an opposite polarity, means on the top side ofy the insulative supporting member for mechanically and electrically connecting the several electrodes of the one polarity, means for mechanically and electrically connecting the electrodes of the'ropposite polarity, and suspending means attached to the insulatingl block for suspending the assembled element entirely from its upper portion within a bat tery jar.

2. In a primary battery of the'class described, the combination of an assembled element comprising a supporting member formed of a single piece of insulating material and having a plurality of spaced openings, a hanger arranged Vabove said supporting member, a plurality of annular spaced electrodes of similar polarity mechanically Vand electrically kconnected and abuttingv against the under surface of said supporting member, a plurality of annular electrodes of different polarity than the first mentioned electrodes spaced from and interposed therebetween, and means for mechanically and electrically connecting said electrodes comprising a plurality of rods, eachl of said rods being connected to one of said electrodes at its lower end and passing upwardly through one ofthe said openings formed in theV supporting member and being bolted to the said hanger, the said rods de tachably connecting the said hanger to the supporting member.
